D-Glucosamine Sulfate 2KCl
Potassium-chloride-stabilized glucosamine sulfate — the form used in most clinical trials supporting glucosamine's joint-health claims in Europe. The 2KCl co-crystal structure stabilizes glucosamine sulfate (which is hygroscopic and unstable in pure form) so it can be reliably formulated and shelf-stored.
